Advantages of electricity...

• Helps lots of things function. for ex., A.C and T.V
• Makes our lives easier for ex., instead of using a candle you can use a light. Also, instead of wrapping yourself up in blankets you can turn on a heater or turn on a fire place.
• Electricity also saves lives. For instance, if your heart isn't working right you can use a defibulator to help it beat again.

Disadvantages of electricity...

• When too many people use electricity at the same time it goes out.
• U.S. people pay $212 billion on electricity bills every year.
• People who use electricity as a power source are harming the environment because half of the electricity produced in the U.S comes from power plants fueled by coal.

How it is used today-

1. T.V
2. A.C
3. microwave
4. computers

Personal Experience:

In the diagram shown above, you can see that it contains a battery, switch, light bulb and wires. The electric flow going through the wires allow the light bulb enough energy to light up/turn on, and create electricity.
